Vibration level switches

Point level detection of liquids and solids

  • Insertion lengths up to 6 m / 19 ft (liquids) or 80 m / 262 ft (solids)
  • Insensitive to changes of media properties, e.g. density, dielectric constant (εr) or electrical conductivity
  • For high/low level detection, dry-run and overfill prevention even in highly critical applications (SIL) or hygienic environments
